Post WW 2 , some Ex Nazis were located and either killed or bought back to Israel for a trial .
Israel/Mossad were successful in a few cases , but unsuccessful in other cases , like Mengele escaped justice .
Point being that Mossad/Jews never did have any "superpower ability" , so Jews haven't lost their super power ability, because they never had them in the first place .
Did you think that Superman was called Jewperman ?
